NICHOLAS TURBUTT, OF FREDERICKTOWN, MARYLAND.

SPARK-CATCHER.

To all whom t may concern Be it known that l, Nici-roms TURBUTT, oflredericktown, Frederick county, State of Maryland, have invented a newand useful Apparatus for Arresting the Sparks which Usually EscapeThrough the Chimneys of Locomotive or other Engines, called TurbuttsSpark Catcher, which is der scribed as follows, reference being had tothe annexed drawings of the same, making part of this specification. n A

The nature of my invention consists in placing a circular horizontalgrate A in a vertical cylinder I, bolted to the top of the ordinarysmoke boX K in the manner of the common chimney, and in placing aninverted funnel B over said grate, the smaller end of which being thesame diameter as the chimney C, which is inserted into the upper andsmaller part of the funnel, and the larger end of a diameter somewhatgreater than the grate which it covers, and in placing` a horizontalcircular plate D around the chimney, upon which the smaller sparks thatpass through the grate are received and consumed, a perpendicularcircular rim or case E being raised upon said circular plate around theperiphery thereof and rising above an inner circular case or cap F,placed over the top of the chimney C for arresting the sparks.

To enable persons Skilled in the art to make and use this apparatus Iwill proceed to describe its construction and operation.

Figure l is a representation of the outside of the apparatus Fig. 2 is avertical section. Fig. 3 is a horizontal section at the line 2cx of Fig.2. Fig. 4L is a top view.

Similar letters refer to similar parts in the figures.

The vertical cylinder is made of any required diameter and depth and isbolted to the top of the smoke box of the engine. The bars of the grateA are placed parallel at such a distance apart as to arrest the largecinders and riveted to the sides of the cylinder. The inverted funnel Bis made of such diameter at the large end as to cover the cylinder I, towhich it is secured by rivets or bolts. The upper or smaller end of thefunnel is a litt-le less in diameter than the chimney C and is insertedinto the same. The chimney C is made in the usual manner.

The circular case F surrounding the chimney has a cap over its upper endplaced at a suitable distance above the top of the chimney, againstwhich the ascending sparks strike and are turned downward, falling onthe circular plate D, the lower end of said case F being without anybott-om and raised and supported by standards at a suitable height abovesaid circular plate to allow the smoke to pass under its edge and ascendbetween the inner case F and the outer case E and pass off into the airabove through said outer' case, which is open at 'its upper end. Theinner case F is of greater diameter and length than the chimney, and theouter case is of greater diameter and length than the inner case.

The circular plate D which forms the bottom of the outer case E and uponwhich the sparks are collected is secured in a permanent manner aroundthe chimney and small end of the funnel by rivets, braces, &c.

In using this apparatus for house chimneys the grate may be omitted*alsothe inverted funnel.

The invention claimed and desired to be secured by Letters Patentconsists in- The arrangement of the grate A, inverted funnel B circularplate D and rim E around the same in combination' with the ordinarychimney C and case F for arresting the sparks as described.
